Common lancehead
The common lancehead is a highly venomous pit viper that lives in the tropical lowlands of northern South America and on the Caribbean island of Trinidad. It is one of the most common pit vipers in its range and is not endangered. Its venom disrupts blood clotting, which makes its bite especially serious.1

Ako ho spoznať
- Ground colour is olive, brown, tan, grey or yellow, and rarely rusty.1
- The body pattern is a series of blotches that often fuse into bands. The markings are X-like, which is why some local names refer to the letter X.1
- The chin is pale yellow, and a dark stripe runs from behind the eye to the corner of the mouth.1
- The irises are gold or bronze, and the tongue is black.1
- Adults usually measure 75 to 125 cm in total length and are moderately heavy-bodied.1
Často sa zamieňa s: It is often confused with Bothrops asper, which was once included in this species. Most authorities now consider B. asper to be a separate species. This confusion also makes reports of its maximum size unclear.1
Sila jedu
Jed vychádza cez jedové zuby, keď hryzie.
Čo robí jeho jed?
Its venom is haemorrhagic, meaning it damages the lining of blood vessels and uses up the substances that allow blood to clot. Symptoms can include severe bleeding, kidney failure, abnormal clotting, blisters and necrosis (death of body tissue). Bleeding in the brain can also occur. Recovery from the clotting problem has been seen 14 to 30 hours after a bite.1
Aké nebezpečné je pre ľudí?
Nebezpečenstvo pre ľudí: Smrteľne nebezpečnéJedno z najnebezpečnejších zvierat na svete.The bite is serious and can be fatal. Plantation workers are often bitten. Juvenile snakes have more lethal venom that kills more quickly, and people bitten by young snakes are more likely to develop the clotting problem. In a case reported in the Brazilian Amazon, the patient died of a stroke even after antivenom was given. A Mexican polyvalent antivenom tested against it had no effect on the clotting problem.1
Čo robí, keď sa bojí?
It is easily agitated, and it can lie camouflaged for hours, nearly undetectable, then strike at high speed.1
Ak uhryzne
- Drž postihnutého v pokoji a bez pohybu, drž uhryznutú končatinu vo výške srdca, daj dole prstene a všetko tesné a rýchlo sa dostaňte do nemocnice.
Vždy najprv zavolaj na tiesňovú linku (112, 000, 911). Toto sú všeobecné rady prvej pomoci, nie lekárska rada. Základy prvej pomoci
Buď v bezpečí
- Nikdy sa nedotýkaj divého zvieraťa, nechytaj ho ani ho nedráždi, aj keď je malé a aj keď vyzerá, že spí alebo je mŕtve.
- Nechaj mu priestor. Ak nejaké stretneš, zostaň pokojný, pomaly cúvni a nechaj ho ísť svojou cestou.
- Ak ťa uhryzne: zostaň pokojný, nehýb sa, zavolaj na tiesňovú linku (112, 000, 911) alebo sa rýchlo dostaň do nemocnice. Zapamätaj si, ako vyzeralo, fotka pomôže.
Nejde po tebe. Jed používa na chytanie potravy alebo na obranu a oveľa radšej sa schová. Viac o tom, ako zostať v bezpečí

Fakty
An enzyme called reptilase, or batroxobin, is taken from its venom and used in modern medical laboratories to measure fibrinogen levels and blood clotting. The enzyme is not affected by heparin.1
Although it is mostly terrestrial, it is an excellent swimmer and will climb trees when needed to reach prey.1
Females with developing embryos move in and out of sunlight to keep themselves and the embryos at a constant temperature.1
Venom yield averages 124 milligrams, but can reach 342 milligrams.1
Despite the large-scale destruction of rainforests, it is among the most numerous and common of pit vipers.1
